To all 'wwm z may concern:

Be it known that I, GEORGE R. GUILD, a citizen of the United Statesv and an ocer of the United States Army, stationed at Baltimore, Maryland, have'invented a certain new and useful Improvement in Signaling Devices, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, re erence being had to the accompanying drawings, forming part of this specicationD My invention relates to a signaling dedesigned for use in con signaling systems utilized vice particularly nection with the for the control ban railway cars, street cars, and the like, the principall object of my invention being to provide a comparatively simple and ecient signaling device wherein the si al light is readily discernible throughout the daylight period as well as at night, such result being attained by means orn a reflector positioned vwithin a housing and disposed asubstantial, distance to the rear or an opening in the wall of the housing, and a source of light arranged so that its rays are thrown directly onto said reflector.

A further object of my invention is to provide a signaling device, including a source of light, a lens, and a reflector, the same being combined and arranged within a suitable housing, the reiiector are transmitted by the cernible at a considerable lens, is readily disdistance away Y from the device, and likewise readily discernible from any point in front of the signal within comparatively wide vertical and horizontal angles.

ly improved signaling device is primarily intended to take the place of the well-known bullseye or target signal devices now in general use in railway signaling systems and the like, and in this connection it will be understood that in practically all of these bulls-eye or target signals, a source of light is positioned directly behind a lens, the latter bein located in the wall of a housing and whide such signaling'devices are effective at night, they cannot be advantageously used daylight period for the reason that the suns rays or rays of light which may pass of railway trains, interur-l so that thesurface of onto which the rays of light during the through the lens and into the housing counteract the light rays from the lamp within said housing. Furthermore, the so-called target or bulls-eye signal lamps can only position, or from points wlthin a limited area, directly in front of the lamp, and for this reason, such Asignal lamps cannot be used adjacent to those por-1 tions ot a railway track containing comparatively sharp curves or on switches and turnouts, 4

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement oi" parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in whichigure 1 is` a vertical section taken through the center of a signaling device of my improved construction;

Fig. 2 is a front elevational view of the housing containing my improved signaling device with apart thereoi` in section;

Figs. 3 and 4 are diagrammatic views illustrating the comparatively wide vertical and horizontal angles through which the reflector of my improved signaling device may be observed, p

Referring by numerals to the accompanying drawings and particularly Figs. l and 2 which illustrate a practical embodiment of my invention, 10 designates a housing of any desired size and shape, and formed in the front wall thereof near the top is Ian opening 11. Arranged within the housing directly behind the opening 11 is a frame l2 which carries on its front side a comparatively dat convex reector 13. 4This frame and reflector normally occupy an angle of approximately forty-live degrees, and this angular position can readily be adjusted by virtue of the fact that the top and bottom of rame'lQ are provided with pivotally mounted buttons 14, the heads of which are arranged to slide freely between suitable guides 15, the latter being applied to the top and rear wall of housing 10.

Mounted for sliding movement between guides 16 on the bottom of the housing is a standard 1'? to which is pivotally connected in any suitable manner an ear 18 which depends from a cup-shaped reflector 19. Removably positioned in the bottom of'this cup-shaped reflector. is a source of light, preferably an electrlc lamp 20, the same be observed from a
